Enables tracing panic hook in addition to pageserver introduced in #3475: - proxy - safekeeper - storage_broker For proxy, a drop guard which resets the original std panic hook was added on the first commit. Other binaries don't need it so they never reset anything by `disarm`ing the drop guard. The aim of the change is to make sure all panics a) have span information b) are logged similar to other messages, not interleaved with other messages as happens right now. Interleaving happens right now because std prints panics to stderr, and other logging happens in stdout. If this was handled gracefully by some utility, the log message splitter would treat panics as belonging to the previous message because it expects a message to start with a timestamp. Cc: #3468
Proxy
Proxy binary accepts --auth-backend CLI option, which determines auth scheme and cluster routing method. Following backends are currently implemented:
- console new SCRAM-based console API; uses SNI info to select the destination project (endpoint soon)
- postgres uses postgres to select auth secrets of existing roles. Useful for local testing
- link sends login link for all usernames
Using SNI-based routing on localhost
Now proxy determines project name from the subdomain, request to the round-rice-566201.somedomain.tld will be routed to the project named round-rice-566201. Unfortunately, /etc/hosts does not support domain wildcards, so I usually use *.localtest.me which resolves to 127.0.0.1. Now we can create self-signed certificate and play with proxy:
openssl req -new -x509 -days 365 -nodes -text -out server.crt -keyout server.key -subj "/CN=*.localtest.me"
start proxy
./target/debug/proxy -c server.crt -k server.key
and connect to it
PGSSLROOTCERT=./server.crt psql 'postgres://my-cluster-42.localtest.me:1234?sslmode=verify-full'
